Tressa Montalvo gave birth to quadruplets on Valentine's Day in Houston. The quadruplets are actually two sets of identical twins. According to a report by the Houston Chronicle, dated Feb. 18, the chances of quadruplets being two sets of identical twins is extremely rare.
Ace and Blaine were the first set of twins born. Cash and Dylan followed, about a minute later. Tressa Montalvo did not take fertility drugs and the boys were not conceived by in-vitro fertilization. If she had used in-vitro, the chances of her having quadruplets that resulted in two sets of identical twins would have been 1 in 10,000. Because the quadruplets were conceived naturally, it was even more rare.
“I can't imagine having four babies at one time,” Candy Roberts, from Warr Acres, said. “My cousin had twins, a boy and a girl. They are a handful. Four boys at one time. I think I would go crazy.”
Most quadruplets split from one egg and will grow in one placenta. This was not the case with Tressa Montalvo's quadruplets. Ace and Blaine were split from one egg and shared a placenta. Cash and Dylan also were split from one egg and they shared one placenta.
“I think the chances of both sets of twins being boys would make this even more strange,” Roberts continued. “I would think that at least one set would have been girls.”
Ace, Blaine, Cash and Dylan were welcomed into the world by their father, Manual Montalvo, and their older brother, Memphis, who is two. The quadruplets are currently at a Houston hospital in the neonatal intensive care unit.
